ANTIFRICTION- BEARING.

SPECIFICATION forming part of Letters Patent No. 694,608, dated March 4., 1902. Application filed August 27, 1900. Renewed August 8, 1901. $eria1No. 71.404. (No model.)

T at whom it may concern.-

7 Be it known that I, WILLIAM J. BREWER, a subject of the Queen of Great Britain, residing at Washington,in the District of Columbia, have invented certain new and useful Improvements in Antifriction-Bearings for Fly-W heels and Similar Machinery; and I do hereby declare thefollowing to be a full, clear, and exact description of the invention, such [0 as will enable others skilled in the art to which it appertains to make and use the same.-

My invention relates to improvements in antifriction bearings for fly Wheels and revolving surfacesgenerally; and it consists of r 5 the construction and arrangement of parts, which will be hereinafter fully described and claimed.

Reference is had to the accompanying drawings, in which the same parts are designated by the same letters of reference throughout the several views, and in which- Figure 1 represents a section through the device, taken along the line 1 l in Fig. 2, looking in the direction of the arrows and show- 2 5 ing the antifriction-rollers in side elevation.

Fig. 2 represents a section through the easing, showing the interior parts in elevation looking at the left-hand side of the device as shown in Fig. 1. Fig. 3 is a view similar to Fig. 1 and represents a slight modification of the device, the section being taken on the line 3 3 of Fig. 4 looking in the direction of the arrows. Fig. 4. is a view looking at the left-hand side of the device as shown in Fig.

3, the casing being omitted. Fig. 5 is a detail edge view of one of the rollers. Fig. 6 is a side elevation, partly in section, of the chain used'in the form of bearing shown in Figs. 1

to 4. Fig. 7 is a transverse section of the same. Fig. 8 is a similar view of a slightlymodified form of chain. Fig. 9 represents a 'section similar to Fig. 1, the casing being omitted, of a modified form of bearing in which a ringis used in place of the chain, the

shaft being shown in section. Fig. 10 is a view of the same looking at the left-hand side of the device as shown in Fig. 9. Fig.

11 is a detail view showing the roller in edge elevation, the ring in section, and a part of the shaft as used in the device as shown in Figs. 9 and 10.

A designates a shaft which may carry a fiywheel A or any other rotating device, the said shaft extending through openings B in the vertical supporting-plates Band being supported out of contact with the sides of the opening B by the antifriction-rollers C, which arejournaled in jou rnal-boxes c, fitted in s'lots b in the supporting-plates l3.

The supporting-plates B are inclosed with- 69 in a casing :19, or they may be made a part of said casing, as will be obvious, and the said supporting-plates are provided with vertical slots or slideways t which do not open through the plates, but are deep enough to 6 form guideways for the journal boxes 0.

(Shown in dotted lines in Fig. 1.)

The rollers C are provided with flanges C, which carry the weight of the shaft A, and theyare grooved, as at 0 to receive a continu- 7 ous body, which may be a band or sprocket chain D, whichincloses and connects together the said rollers C, causing all the rollers to turn 7 together.

The sprocket-chain D is formed of a series of blocks cl, connected together by narrow links 01, of any suitable material, either elastic or substantially non-elastic. The blocks (1 are Wedge-shaped in cross-section, as shown in Fig. 7, and arranged to fit in the V-shaped 8o groovesc in the rollers C. These grooves 0 however, are a little deeper than the blocks d,'so that the apices of the blocks do not quite touch the bottom of the grooves.

In the form of device shown in Figs. 1 and 8= 2 three antifriction rollers are employed,

'journaled in the journal-boxes c, which are placed in the slots b the lower roller C, which carries the weight of the shaft, being placed in the middle slots, which are directly be- -neath the shaft and extend lower than the slots at the sides of the shaft, the bottoms of the said middle slots forming supports for the journal-boxes c of the said lower roller. The journal-boxes c of the side rollers are 7 held in the slots 12 at the sides of the shaft A,

and these side rollers prevent lateral movement of the shaft, the three rollers being held from spreading by a continuous body D,which may be either a band or chain, which incloses all three rollers, as hereinbefore described.

In Figs. 3 and 4 four rollers C are employed, and the four are held in proper relative position by retaining-rings E, in which the said rollers O are journaled, the continuous body in this instance passing around all four of the rollers to turn all of them together and at the same speed.

In the device as shown in Figs. 3 and 4 the rollers and their retaining-rings are placed within the casing X, the journals 0 of the rollers extending through the retaining-rings far enough to enter the guideways b in the supporting-plates B. The guideways b in this form of device are so placed that one of the rollers will be beneath the shaft, the two side rollers will have their centers in the same horizontal line with the shaft, and the upper roller will be above the shaft. The upper roller having very little work to do will require no other bearing than that afforded by the retaining-ring E.

In practice the casing X is filled with oil about as high as the line 00. Thus the lower roller which carries the weight of the shaft is nearly immersed in oil, while the oil carried around by the chain will be sufficient to lubricate the other rollers. The two upper rollers O are provided with oil-ducts (shown in Figs. 1 and 5,) which allow the oil from the chain to pass to the journals of the rollers. A cover X (shown in Figs. 1 and 3) is placed over the casin g to prevent the oil from splashing out and also to exclude dust.

In the modification shown in Figs. 9 and 10 there are also four rollers O employed, and they are journaled in a frame F and may be supported in any suitable manner-as, for instance, in this latter form the frame F, containing the rollers, may be placed in a easing X, similar to that shown in Fig. 3, which easing, however, is not shown in Fig. 9. In this form of the device the shaft A is provided with an annular rib or collar a, which is V-shaped to enter the V-shaped groove 0 in the rollers O to prevent endwise or longitudinal movement of the shaft, the weight of the shaft being carried by the flanges C. In this latter form the continuous body surrounding the rollers O is shown as a ring or band II, which is V-shaped in cross-section, as shown in Fig. 11, and incloses the rollers C, turningwith them and causing all of them to turn at the same speed. This band H may be a metallic ring or it maybe made flexible, as maybe found most advantageous in practice.

Having thus described my invention, what I claim, and desire to secure by Letters Patent of the United States, is

and a continuous bodyinclosing said rollers; substantially as described.
